Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The application provides a method for eliminating noise of electrostatic dust removal equipment, which is particularly suitable for electrostatic dust removal equipment working in a humid environment. This application forms electrically conductive water film layer on electrostatic precipitator's style electrode, and through electrically conductive water film layer release electric charge, avoid the electric charge to pile up, reach the effect of eliminating the discharge noise.
This application mainly provides two kinds of different modes and realizes the noise abatement: (1) the surface of the style electrode is treated to form a water-soluble salt layer, so that a conductive water film layer is formed on the surface of the style electrode when the electrostatic dust removal equipment works in a humid environment. (2) The surface of the style electrode is processed to form a conductive saline film layer, so that the conductive saline film layer is formed on the surface of the style electrode when the electrostatic dust collection equipment works in a humid environment. Wherein, the conductive water film layer comprises salt dissolved in water, and the salt particles are sodium chloride or potassium chloride.
The above two modes are explained in turn as follows. First, the implementation procedure of the method (1) will be described.
Referring to fig. 1, the method for eliminating noise of the electrostatic dust collection device comprises the following steps:
step 101: a textured electrode is prepared.
The style electrode 11 is divided into a positive style electrode and a negative style electrode, the positive style electrode is connected with a positive voltage, and the negative style electrode is connected with a negative voltage. In fig. 2, the left-hand patterned electrode is a negative patterned electrode, and the right-hand patterned electrode is a positive patterned electrode.
In this embodiment, if the patterned electrode 11 is already installed on the electrostatic dust removal device, the patterned electrode 11 on the electrostatic dust removal device is removed, and then a water-soluble salt layer is prepared on the surface of the patterned electrode 11. If the patterned electrode 11 is not installed on the electrostatic dust removal device, the water-soluble salt layer is directly prepared on the surface of the patterned electrode 11.
Step 102: and soaking the style electrode in a salt solution to form a water-soluble salt layer.
Referring to fig. 3 and 4, the salt solution 12 includes salt particles 121. Preferably, the salt particles 121 may be sodium chloride. In other embodiments, the salt particles 121 may also be soluble salt particles 121 such as potassium chloride, calcium nitrate, ferrous sulfate, ammonium calcium sulfate acetate, copper chloride, sodium acetate, and the like, which is not limited in this application.
In a practical application scenario, the salt particles 121 and water are mixed to obtain the salt solution 12 with a predetermined concentration, and the predetermined concentration of the salt solution 12 may be set according to specific situations, which is not limited in this application. The textured electrode 11 is immersed in a salt solution 12 to form a water-soluble salt layer. The soaking time can be set according to practical situations, such as 1 hour, 2 hours or other times, which is not limited in this application.
Then, the patterned electrode 11 is taken out of the saline solution 12, and the patterned electrode 11 is dried to precipitate the salt in the saline solution 12, wherein the salt in the saline solution 12 adheres to the patterned electrode 11 in the form of particles (salt particles 121) to form a water-soluble salt layer. The drying process of the patterned electrode 11 may be heating, air drying, or the like, but is not limited in the present application.
Step 103: and mounting the style electrode on an electrostatic dust removal device.
In a specific application scene, water-soluble salt layers are formed on the surfaces of the positive grid electrode and the negative grid electrode, and the positive grid electrode and the negative grid electrode are installed on the electrostatic dust removal equipment. Meanwhile, the positive grid electrode is connected with a positive voltage, and the negative grid electrode is connected with a negative voltage.
Step 104: and starting the electrostatic dust removal equipment.
Step 105: the air inlet of the electrostatic dust collection equipment sucks air containing water vapor, the water vapor is adsorbed on the surface of the style electrode, and the water-soluble salt layer is dissolved with the water vapor to form a conductive water film layer.
In this embodiment, as shown in fig. 5 and fig. 6, the electrostatic dust removal device is started, the air inlet of the electrostatic dust removal device sucks air containing water vapor, the water-soluble salt layer is dissolved with the water vapor to form a conductive water film layer, and the conductive water film layer can conduct current (similar to grounding), so that charge accumulation is avoided, and the effect of eliminating discharge noise is achieved.
The salt particles are exemplified herein as sodium chloride 121. As shown in fig. 5 to 9, after the styling electrode 11 is mounted on the electrostatic precipitator 10 according to the above-described method, the electrostatic precipitator 10 is started. The electrostatic precipitator 10 draws air 19 from the air inlet of the styling electrode 11.
In a humid environment, the air 19 has a high moisture content. When water vapor in the air 19 meets the sodium chloride 121 particles on the patterned electrode 11, a mist-like sodium chloride 121 solution (conductive water film layer) is formed.
The electrostatic precipitator 10 further includes a filter 13, and the filter 13 is used for filtering dust in the air, filtering larger granular dust, and letting only smaller granular dust 131 enter the styling electrode 11.
Because of the large electric field formed between the positive and negative electrodes, corona is formed near the negative electrode (as shown in fig. 8), that is, air near the negative electrode is ionized, and ultraviolet rays are emitted. That is, a layer of light purple charged air is provided around the cathode, which is called corona.
The dust 131 is combined with the charge 14 (negatively charged), and under the action of the electric field, the combined dust 131 and charge 14 move toward the positive grid electrode (in the direction of the arrow shown in fig. 8) and are adsorbed onto the positive grid electrode (as shown in fig. 9). Because the sodium chloride 121 solution is conductive, the sodium chloride 121 can adsorb free charges 14, release the charges, avoid the accumulation of the charges and achieve the effect of eliminating the discharging noise.
Further, when the electrostatic precipitator 10 stops operating, the atomized sodium chloride 121 solution adheres to the styling electrode 11. After the sodium chloride 121 solution attached to the textured electrode 11 is dried, the sodium chloride 121 solution is attached to the textured electrode 11 in the form of sodium chloride 121 particles, and waits for the next action. The solution of sodium chloride 121 attached to patterned electrode 11 may be dried by heating or air drying, but is not limited in this application.
The implementation of the mode (2) is briefly described below. The mode (2) is mainly used for a scene that the style electrode is installed on the electrostatic dust removal equipment, or after the style electrode manufactured in the mode (1) is used for a long time, a salt layer is possibly thinned and cannot achieve a good noise elimination effect, and the mode (2) can be adopted for spraying the salt solution to form a conductive salt water film layer on the style electrode, so that a conductive water film layer is formed on the surface of the style electrode of the electrostatic dust removal equipment when the electrostatic dust removal equipment works in a humid environment.
Specifically, in the present embodiment, a salt solution is applied to the textured electrode by spraying to form the conductive saline film layer. Specifically, after the electrostatic dust removal equipment works and when the electrostatic dust removal equipment starts to work, the conductive salt solution spray is sprayed at the air inlet, and the spray is absorbed and then condensed and adsorbed on the style electrode to form a conductive water film layer. Because of the electric conduction, the electric charge is not accumulated on the conductive water film layer any more, the discharging condition is lost, and the function of eliminating the static noise is achieved.
The present application provides a patterned electrode, which is the patterned electrode in the above embodiments, and a conductive salt water film layer or a water-soluble salt layer is disposed on the surface of the patterned electrode.
The application provides an electrostatic precipitator equipment, electrostatic precipitator equipment includes foretell style electrode.

This application forms electrically conductive water film layer on electrostatic precipitator's style electrode, and through electrically conductive water film layer release electric charge, avoid the electric charge to pile up, reach the effect of eliminating the discharge noise.
